For a long time, the prosperity of the doors and windows industry mainly benefited from two major factors: First, the increase in urbanization rate, with hundreds of millions of people moving into cities, contributed to the huge demand for decoration. According to data from the Seven Census, my country's urbanization rate has increased from less than 50% in 2010 to 63.89% in 2020, which has not only driven the prosperity of real estate, but also contributed to the hot sales of doors and windows. Second, new commercial housing has continued to grow at a high rate for many years. According to data from the Sixth and Seventh Censuses, the total housing stock for urban households in 2010 was 17.9 billion square meters. By 2020, it had grown to 29.46 billion square meters, equivalent to a net increase of 11.56 billion square meters in 10 years.

Behind the above two types of data, both mean a very considerable demand for doors and windows, and also indicate that the stock of old houses built 10 or even 20 years ago has reached a huge scale. Some of the old houses have doors and windows with low energy-saving standards, aging and disrepair, poor sound insulation and thermal insulation performance, and potential safety hazards from falling, and are entering a vigorous stage of renovation.

As time goes by, more old houses will be renovated and will enter the demand release stage, forming a new growth engine for the doors and windows industry. Behind this judgment, in addition to the above data support, there is more evidence:

First, there are nearly 160,000 old residential areas in my country before 2000, involving more than 42 million residents and a construction area of ​​about 4 billion square meters. At the same time, our country will complete these old residential areas during the "14th Five-Year Plan" period. The renovation of old residential areas may trigger the need for replacement of doors and windows. Hao Jiping, a professor at Xi'an University of Architecture and Technology and president of the China Construction Metal Structure Association, once suggested that subsidies for doors and windows should be provided when promoting the renovation of old urban residential buildings. If the policy can be implemented, it will be a great benefit to the doors and windows industry.

Second, based on market data, among the customers of many home building materials brands and dealers, existing housing stock, including old communities, accounts for more than 70%.

Analysis from Jianrong Investment shows that between 2021 and 2030, the compound growth rate of demand for renovation of existing housing will be 6.72%.

At the same time, the total number of existing housing units in need of renovation will reach 99.32 million units. Among them, the replacement of doors and windows will maintain a certain proportion. If calculated at 10,000 yuan per household, it can also bring a demand scale of nearly one trillion yuan. In fact, when some well-known brands promote whole-house door and window packages, the total price is set at around 19,800 yuan.

Affected by factors such as the upgrade of residential consumption and the expansion of the base of middle- and high-income groups, door and window brands with strong influence will win the favor of customers who renovate old houses.

Products, solutions and services that meet the needs of old house renovation are likely to seize the opportunity to the greatest extent possible.

In this regard, there are many door and window companies that have started renovating old houses, and their methods are concentrated in three types:

The first is to launch exclusive products and solutions for the renovation of old houses, such as special renovation packages.

The second is to open stores in communities where old houses are densely distributed to strengthen market penetration.

The third is a targeted marketing strategy for old house renovation.
